川西北地区引进甘薯品种筛选研究

[目的]筛选适宜川西北地区种植的优质高产甘薯(Ipomoea batatas Lam.)品种。[方法]对引进的8个甘薯品种(南薯007、泉薯9号、渝5-12-57、川12-17、浙薯23、E01-09、宁23-1、浙薯70)进行栽培试验,以南薯88为对照。采用随机区组排列,3次重复。[结果]宁23-1、浙薯70鲜薯产量比南薯88分别增产4.91%和1.72%,浙薯70、川12-17淀粉产量比南薯88分别增产24.46%、24.10%,达到极显著水平。[结论]宁23-1、浙薯70、川12-17综合性状均较优良,可以在今后的生产中进行大面积推广与种植。

Study of Sweet Potato Varieties(Ipomoea batatas Lam.) Introduction and Comparative Study in Northwest Sichuan

[Objective] The purpose was to select the high-yield sweet potato varieties suitable for northwest Sichuan planting.[Method] Cultivation test for introduced eight sweet potato varieties,Nanshu 007,Quanshu No.9,Yu 5-12-57,Chuan 12-27,Zheshu 23,E01-09,Ning 23-1,Zheshu 70,were carried out through randomized block arrangement with three repetitions taking Nanshu 88 as control.[Result] Comparing with Nanshu 88,the fresh sweet potato yield of Ning 23-1 and Zheshu 70 increased 4.91% and 1.71% respectively,the starch yield of Zheshu 70 and Chuan 12-17 increased 24.46% and 24.10%respectively,arriving highly significant difference level.[Conclusion] The complex traits of three varieties,Ning 23-1,Zheshu 70 and Chuan 12-17,are all excellent,can popularize and plant in a large scale in future production.
